The utility model discloses a bottom molding block mechanism for an injection blow molding machine, comprising a movable mold main body and a servo motor. A left fixed plate is installed on the right side of the movable mold main body, a connecting shaft is installed inside the left fixed plate, a servo motor is installed at the top end of the connecting shaft, a rotating gear is fixed on the outer side of the bottom end of the connecting shaft, a tooth block is meshed and connected to the outer side of the rotating gear, a movable blowing block is fixed at the bottom end of the tooth block, and a fixed blowing block is arranged on the right side of the movable blowing block. The bottom molding block mechanism for the injection blow molding machine is provided with a rotating gear and a tooth block. The rotation of the rotating gear drives the meshed tooth block on the outer side to move, so that the tooth block well drives the movable blowing block to rotate, and the movable blowing block drives the bottom molding block main body of an integrated bottom structure to rotate together. Therefore, compared with direct leftward movement to separate from the molded material, such rotation first and then leftward movement can well protect the bottom of the molded material.
